This is USB 2.0 type A to micro USB 5-pin cable. It might not be a new standard nowadays, but I am pretty sure many devices still use USB microB as power receptor to charge battery, as data communication like NodeMCU, Maker UNO, CT-UNO. Micro USB connectors are about half the height of mini USB. Micro USB is found on newer hand held devices like cell phones and portable media devices. Works great with the Google Nexus One and of course the famous Arduino Leonardo.

Picture above shows this USB Micro B Cable used with Cytron UNO, which have extra standard pads for those who wanted to create their own shield.
